摘要
针对西部大开发中广泛的岩土工程问题提炼出四个有代表性的岩土力学问题 ,就该岩土力学问题的研究现状、存在的困难、发展方向等进行了探讨 ,可望对这一问题引起抛砖引玉的深究。
The state of arts for the special geomechanic problems for loess,frozen soil,and jointed rock materials encountered in civil construction in the Western Development of China,is presented and discussed deeply.The author believed:(1)the most important research for loess is the micro structural features of the loess;(2)the most reliable research for frozen soil should be the further experimental studies on the coupled behaviors of the water migration,heat transfer and thawing deformation of the freezing soil mass instead of frozen soil sample;(3)the most difficult and most reliable study on jointed rock materials is the dynamic properties of the jointed medium instead of the continuous medium or the static properties of the jointed materials;(4)the most urgent research should be the dynamic stability analysis theory of the high arch dams under earthquake loadings.
